I'm sorry, but this is not confusing or convoluted. It's fairly basic. It should take seconds to find the way to the mods folder the bat file made, open explorer, then paste this in the address bar and hit enter: %APPDATA%\Strive . I can't comprehend how that takes 4 minutes to find, unless it takes you 1 minute to move and click your mouse or press buttons on the keyboard for each action. We've been repeating this same thing over and over here. This %APPDATA% folder is also where a bunch of other game's data often end up, including save files. You'll want to get used to finding it, or understanding how to enter in paths like this in windows explorer.
At this point I'm not sure it makes sense to explain further, you don't seem to be capable of following directions, considering we've explained what goes in this folder before, but here I go:
It has a mods folder, then in that folder you extract the mod, the mod should have it's own folder, containing an info.txt file. Full path you end up with is:
%APPDATA%\Strive\mods\randomportraits\
and in there you'd see an info.txt file.
Then for portrait packs , their zip file usually contains the Bodies and Portraits folders. You want to copy those into the Strive folder, so you end up with:
%APPDATA%\Strive\Portraits\
%APPDATA%\Strive\Bodies\
One thing to note, itch's forums kinda suck for copy and pasting text. It often inserts random unicode characters. If those end up getting copied, then things might not work quite right. Did my best to try and avoid that with these. However if any of these don't behave right, try to delete characters before the % or after the \ that may be there, but hidden.
